A digital camera and an operating method thereof are disclosed. The digital camera includes an image sensing module, a display, an operating element, and a control module. The image sensing module consists of N pieces of image sensing elements. The display is used to show a first image. The operating element is used by a user to select a specific area in the first image and set correction parameters for the specific area. The control module is connected to the image sensing module and the display for obtaining information about a position of the specific area relative to the first image and the correction parameters, and uses the obtained position information and the correction parameters to control M pieces of the image sensing elements in the image sensing module corresponding to the specific area, so that a second image is obtained based on the correction parameters.
